Nix Capture

Product Introduction

1. Definition: Nix Capture is a browser extension (Chrome) for technical diagnostics, specifically capturing HTTP/HTTPS network requests during user sessions. It operates as a zero-configuration debugging tool that records API endpoints, status codes, headers, and payloads without accessing browser DevTools.
2. Core Value Proposition: It eliminates friction in bug reporting by automatically capturing full network context (XHR/fetch requests) for developers, enabling faster issue resolution. Primary keywords: network request capture tool, automated bug reporting, technical evidence for developers.

Main Features

1. One-Click Session Recording:
   • How it works: Activates via Chrome extension icon, intercepting all network traffic using the WebRequest API. Records URL endpoints, methods (GET/POST), status codes (200, 404, 500), latency, and payloads.
   • Technology: Chrome’s debugging protocols filter OPTIONS preflight, images, and static assets by default.
2. Smart Request Filtering:
   • How it works: Auto-ignores non-essential resources (CSS/fonts) and focuses on XHR/fetch API calls. Users toggle "XHR Only" mode to isolate backend communication.
   • Technology: Pattern-matching algorithms categorize requests by type and domain.
3. Multi-Format Export (cURL/HAR/JSON):
   • How it works: Exports captured sessions as executable cURL commands (for replication), HAR files (for DevTools import), or raw JSON. Includes headers, cookies, and timestamps.
   • Technology: Data serialization via browser-native APIs ensures compatibility with Postman or Charles Proxy.

Problems Solved

1. Pain Point: Incomplete bug reports lacking URLs, status codes, or request bodies force developers to manually reproduce issues, wasting 15-30 minutes per ticket.
2. Target Audience:
   • QA Engineers needing reproducible technical evidence.
   • Support Teams documenting customer-reported bugs.
   • Product Managers verifying UI/API issues without coding skills.
3. Use Cases:
   • Capturing 4xx/5xx errors during checkout flow failures.
   • Logging slow API responses causing UI timeouts.
   • Exporting authentication token mismatches in session requests.

Unique Advantages

1. Differentiation vs. DevTools: Unlike manual DevTools (requiring technical expertise), Nix Capture offers one-click operation with curated outputs. Competitors like HTTP Toolkit lack browser-native simplicity.
2. Key Innovation: Local-only data processing ensures zero data leaves the device (unlike cloud-based alternatives). Noise reduction algorithms prioritize actionable API calls over static assets.

Frequently Asked Questions (FAQ)

1. How does Nix Capture ensure data privacy?
   All network data is processed locally—no uploads to external servers, complying with GDPR/CCPA.
2. Can Nix Capture record GraphQL or WebSocket requests?
   Currently supports HTTP/S and REST APIs; WebSocket/GraphQL capture is roadmap-planned for v1.0+.
3. Is Nix Capture compatible with Jira or GitHub Issues?
   Export HAR/JSON files attach directly to tickets in Jira, GitHub, or linear.app for developer analysis.
4. Does it work on all websites?
   Functions on 99% of sites except those blocking extensions via CSP headers (e.g., banking portals).
5. How to share captured sessions with developers?
   Export cURL commands for terminal replay or HAR files for Chrome DevTools import.
